I thought I'd write about my experiences with wardriving and mapping the results, and see if anyone else has come up with a similar or better way of doing it.
As part of some University research I am doing, I regularly do wardriving and logging of 802.11b networks with Netstumbler. I wanted to be able to plot the access points on a map, but couldn't find a suitable software package until another student suggested Tumonz. (http://www.tumonz.co.nz/
Well, it's fantastic and has the level of detail I need right down to individual streets. Being vector graphics, the detail is excellent when you zoom in.
However, one shortcoming I found is that Tumonz has no open or save feature (that I have found anyway). This means, to get the Netstumbler log file into Tumonz is a little convoluted, but it does work.
You need to have a GPS (I've only tried a Garmin) to log the Latitude and Longitude of the access points.
Here's what I do:
1> Export the Netstumbler file in Summary format.
2> Use mapsstumbler (free to download) to convert the ns1 file to a wpt file.
3> Import the wpt file into Garmin Mapsource World. (may work with others) Mapsource include NZ, but is high level and doesn't show the streets.
The nice thing about the conversion is that it distinguishes between encrypted and unencrypted on the waypoint plot.
4> Now that you have the waypoints in Mapsource, upload them into the GPS. (The GPS won't log the waypoints as you find the access points)
5> Download the GPS waypoints into Tumonz. You need a Garmin or Magellan GPS for this. Infortunately, it doesn't keep the encrypted / unencrypted information.
The access points will now be plotted on a New Zealand map at a street level. Good stuff, but saving the files seperately in Tumonz is another bit of trickery.
